Research Interests

– Current research focus on fundamental investigations of the local dependence of plasmonic structure and tailoring thereof, in 1D semiconductor assemblies, carbon nanotubes, graphene and other novel 2-D materials, aiming at practical use in photo-emission, optical enhancers, wave guides, photovoltaics, and at design of prototype devices.- Sustained high quality publication output (~170+ papers; major investigator and writer in 80% of these) in academic/ professional journals, including Nature papers, review articles, Perspectives, and over 45 refereed conference papers; (not including 100 or so un-refereed conference papers); contributed prolifically at national and international conferences, delivered numerous invited talks and seminars- Highlights of recent research include •international reputation in pioneering studies of the relationship between microstructural defects and electronic band structure in semiconducting and wide bandgap materials via valence band electron energy loss spectroscopy (VEELS) •amongst the first to achieve single atom electron spectroscopy with single atom imaging resolution •first to apply VEELS to graphene and to attempt plasmon tailoring in carbon nanotubes and graphene (via ion implantion) •first in atomic resolution high angle dark field imaging and energy loss spectroscopy of graphene, revealing insights into the atomic structure (defects, ad-atoms, impurities), the dynamics of the topography (rippling, nano-scopic metal-atom assisted etching, graphene defect healing) •first to use ion implantation to controllably functionalise graphene •first, with colleagues from PSI, to demonstrate Scanning Tunneling Microscopy of suspended graphene and static nature of its ripples

– Current application-oriented research objectives are •novel 2-D versions of dichalcogenides (including materials with negative plasmon dispersion for direct light coupling) and of MAX phases (MXenes ->unknown territory) •carbon nanotubes: ion beam modification for application as optical enhancers, wave guides, photonic and light harvesting devices (plasmon tuning); evolution of morphology and influence on electronic properties for integration into semiconductor electronics •Silicon photonics for Si-integrated technologies: light emission from the rare-earth doped silica/Si-nanoscrystal system through ion-beam modification

– Past research has included •role of defects in the ageing and failure mechanisms of semiconductor devices •exploration of electron microscopies/ spectroscopies with ultra-high spatial resolution applied to materials of wide and medium bandgaps – highly spatially resolved chemical and electronic structure studies via EELS •self-organized growth phenomena in strained III-V semiconductor hetero systems and SiGe

•establishing a universal roughening transition curve (temperature versus strain) •strain driven compositional segregation in semiconductor quantum wells, wires and dots •bandgap states at extended defects in wide band gap semiconductors, diamond and perovskites •surface plasmon phenomena in nanocarbons, semiconductor and metal nanospheres
